Diutina

Two species previously classified in the genus Candida have now been transferred to the genus Diutina.Diutina catenulata (formerly Candida catenulata) and Diutina rugosa complex (formerly rugosa complex).

Key Features:Separation from most physiologically similar species can be accomplished based on positive growth responses on D-mannitol, D-glucitol and resistance to 0.1% cycloheximide, combined with negative responses for sorbose and erythritol utilisation or growth in vitamin-free medium.

Diutina rugosa has recently been recognised as a species complex of D. rugosa, D. pseudorugosa and another as yet undescribed species (Li et al. 2006, Paredes et al. 2012). These species are best identified by ITS sequencing.
